NOTES: This steel-framed building was designed on two floors around a central courtyard according to American out-of-town planning principles by the Chicago firm of Skidmore Owings & Merrill (SOM) in association with the London firm of Yorke Rosenberg Mardall. This extremely influential building with its use of high-class welded steel and the open-plan design led the way for the subsequent development of 'high-tech' steel office buildings for which Britain became internationally renowned. It was Grade II listed in 1996.
NOTES: This was James Wyatt's last great Gothic house, finished on his death by his nephew Jeffry Wyatt (later Sir Jeffry Wyatville) who added the lower buildings on the right in the drawing. See RIBA95235 for Buckler's view of the house from the south-east at the time of Wyatt's death.
